Filmmaker and Discovery and Science Channel star Les Stroud, known for his show, Survivorman, is calling it quits after three seasons. The 47 year-old Canadian earned street cred amongst survivalists by filming himself completing various week-long survival challenges. Unlike Man Versus Wild’s Bear Grylls, Stroud traveled without a camera crew and survival experts. I, for one, found his solo approach to film-making and survival refreshing compared to Grylls’ preening in front of the camera.

Stroud explained his decision to call it quits to Reuters: “You can only do seven days surviving without food a certain number of times a year. I’m pleased with what I have done, I’ve been copied around the world, but 25 times I’ve not eaten anything for a week while sleeping on rocks. I need to move on.”

Filming for the third, and now final, season is wrapping up in Papua this month. Though the tag Survivorman will probably always remain with him, Stroud plans to move on to other projects. He is writing a book about wilderness survival and is planning a new show where he will follow in the footsteps of famous explorers.
